namespace App\Http\Middleware;
use Closure;
class Cors
{
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $response->header('Access-Control-Allow-Methods', 'HEAD, GET, POST, PUT, DELETE');
        $response->header('Access-Control-Allow-Headers', $request->header('Access-Control-Request-Headers'));
        $response->header('Access-Control-Allow-Origin', '*');
        return $response;
    }
}

@CrossOrigin(origins = "http://localhost:4200")
@GetMapping("/yourPath")
